About
You didn’t come to Thumbtack for more confusion. You came to find someone you can actually trust. We get it. Most accounting help online is either overpriced, under-delivered, or full of jargon. At MASCPA, we’re different, on purpose. Led by Mark A. Stiles, CPA, MASCPA is a virtual, full-service firm with over 20 years of experience guiding business owners just like you. We specialize in clarity, not complexity, using a proven framework called the MASCPA Box Method to connect your books to your goals, and your taxes to your peace of mind. We’re more than bookkeepers. We’re strategic partners who meet you where you are, clean up the mess (without judgment), and help you lead with financial confidence. What Makes MASCPA Different? Founder-first mindset: You’ll never be treated like a transaction. Practical strategy + clean execution: We do the books and build the plan. No jargon, no pressure, just clarity: Even if you’re behind, we can help. The Box Method: Our four-quadrant framework simplifies everything from taxes to growth planning. If you’ve been burned by cookie-cutter firms or left guessing by “cheap help,” MASCPA is your reset button. Let’s rebuild trust and move forward with real strategy, expert guidance, and total transparency.

Mark did a great job from start to finish. He was professional, knowledgeable, and delivered high-quality work. He explained everything clearly, was responsive to questions, and provided excellent value for the service. I would absolutely recommend him and would work with him again.

Incredibly happy that I went with Mark for handling some delinquent filings. After owing a nice little chunk one year, I felt a bit uneasy doing my taxes and created a situation where I was stressed about having not filed. Wanting to make some big changes (buy a home & start a new business), I knew that I just needed to bite the bullet and get it done. I spoke with a number of different CPAs and instinctively knew that I had to enlist Mark. My ultimate goal was to bring everything current and use my personal taxes as a litmus test for future conversations about structuring my business from the start. Let’s just say that Mark surpassed my expectations; he is incredibly personable, direct and knowledgeable. The returns were delivered when as promised and his secure site for exchanging tax documents and completed returns contribute to a true sense of professionalism. (Re)Learned a couple valuable things working with Mark: 1) anticipation of the unknown is much worse than actually doing the thing 2) Mark is definitely my CPA of choice for personal/business returns 3) Will recommend him without hesitation (passed along his info to a friend already)

Mark took care of our tax returns very quickly and efficiently. The BEST part of his service was that he took the time to teach us about what exactly he was doing and how we should manage/allocate our money in the future to determine the best outcome for our annual taxes. My husband and I are a young, newly married couple with children and our future is important to us. If you are looking for someone to TEACH, handle QUICKLY and PROFESSIONALLY then Mark is your guy. We are sticking with him for the long haul and look forward to having a professional accountant take care of our tax needs and assist us with money management for our future.
